{Disarmed} Re: Re: Cult: I. borer ~4th instar

That is interesting Shirley.  I live in Lascassas TN, we have a fair amount of humidity, but in 9 years of iris growing, I have seen one borer.  I really believe it came in on a borer that I bought.  I found it about 2 weeks after I planted it, burrowed about 1/2" into the rhizome.  I was able to save the rhizome, caught it early.  Only one I have ever seen and the members of our iris society in Murfreesboro TN say they just aren't a problem here...........thank goodness.  We are considered Middle TN as far as location is concerned.  South and a little east of Nashville.

From the few years of research I have been doing on the borer, I have found that it seems they only thrive in areas where the humidity is high.  Borers are found in Joplin Mo, but not in Tulsa or points south.  Only change is in humidity.  Borers are found in Kansas City but not in Wichita or points west.  Again, only change is  humidity. East and south into Georgia there is high humidity.  I would like to see further research on where they are and where they are not.  Perhaps we might be able to get some kind of a map together.  That would be of interest and certainly educational.

If there aren't any iris borers in Australia, it is worth any amount of quarantine to keep them out.  So far there are none in southern Arizona.  It is just too hot for them.  At 114 degrees F. it's almost too hot for irises and people too.

Rhonda, as a matter of hygene whenever i cut a rhizome, i always dip
the cut edges in Flowers of Sulphur. This is a proven natural way to
prevent the spread of fungus and other diseases. As yet i have not
come across this borer but i would certainly try the Flowers of Sulphur
and as you said keep a close eye on the plants in Spring. Best of luck
